Does anyone know how French electrical outlets or currents differ from other European countries or America? I've been told they run on 220/50 hz whereas American outlets run on 120/60 hz (if they are up to date). I'm also wondering if there is a converter. Any info would be appreciated.
You are right about voltage and frequency, all Europe has 220V/50Hz. For most appliances (shavers, radios, computers) you don't need a converter, adaptor is OK, mostly it is possible to get them is at the airport. Universal adaptors are an even better option.
Outlets are different in UK, Ireland and Italy, the rest of Europe is more or less compatible.
